TalkTalk router shows red internet light

If your router was previously working and you haven’t added any new phones or moved the phone equipment or router to another telephone socket, then this is a matter that only TalkTalk can resolve. There’s a long shot that it could be your phone wiring but if it was working reliably before then it probably isn’t that.

TalkTalk tech support is on 0870 087 8777. This number is free from a TalkTalk landline. Explain your fault and ask them to do a line test. They will be able to see dropped connections from their end.
